Fix N-dimensional strided loops and extend the alpaka tests

[fwyzard]

PR description:

Implement an N-dimensional vector add test with alpaka and cms::alpakatools utilities.
Refactor the checks for accelerators that support multiple threads per block (e.g. GPUs) or a single thread with multiple elements (e.g. serial CPUs), and use the new constant to simplify the workdiv generation and the strided loops.

PR validation:

The new unit tests pass.
